The Australian rapper tells the Associated Press (via Yahoo) the collaboration — called "Pretty Girls" — will be the first single off her next album, which she hopes will drop this year.

"I love Britney. She's super sweet and I just want to hang out with her all the time," she said in the interview. "I don't know if I needed re-inspiring, but it's just made me extra excited to want to put out new music," she added about the song.

The "Fancy" star, who recently quit social media, said she is enjoying her time away from it and may make it a permanent hiatus. "Yeah, so nice not to be on social media so I'm kind of going to continue that until, maybe forever," she said.

Azalea also provided more details about her postponed her Great Escape tour, noting, "The whole point was to make no compromises, but nothing's changed in terms of my creative vision," she said. "It's very kind of like Patrick Nagel, powerful '80s androgynous women vibe."

Another benefit of pushing the tour back to spring? More freedom to work on her sophomore album.

"I didn't anticipate having any time to completely finish it, but now that I have kind of the time," she said of the potential release. "I'd love to have an album at the end of 2015."
